To all lwhom t may concern.'

Be it known that we, PADIJ DAIMLER and MAX FRIZ, both citizens of Germany, and

cient mechanism 'whereby such motors or. motor groups may be lndivldually or concurrently regulated or controlled asmay be desired, the regulation or control being accomplished for instance through the medium of the vaporizer or carbureter or by regulating the ignition point as the reqnirements of the moment may render necessary. Our invention will be fully described hereinafter and the features of novelty will be pointed out in the appended claims..

In the accompanying drawings which show several examples of our improvement Figure 1 is a side view of one form thereof; Fig. 2 is a sectional elevation showing the parts in normal position; Fig. 3 is a detail horizontal section on the line 3 3 of Fig. 2; Fig. 4 is a view similar to Fig. 1 of another form of our improvement; Fig. 5 is a` sectional elevation thereof; Fig. 6 is a'horizontal section on the line 6-6 of Fig. 4;

Fig. 7 is asectional view of the forni shown in Fig. 4 with the parts in different positions and Fig. 8 is a view similar to Fig. 5 showing the parts in different positions.

Referring to the formshown in Figs. 1-3 which is arranged to control a driving means composed for instance of two individual motors or two motor groups a represents a relatively stationary support of frame suitably supported in voperative position and carrying a shaft ZJv rotatably mounted in .bearings a located on the frame a. A main lever 'c is located upon this shaft b preferably so as to rotate therewith and extends upwardly therefrom and terminates in .an

operating handle cx, auxiliary levers d and d being looselymounted on said shaft at Aopposite sides of and in relatively -closev proximity to the main lever c as shown in Fig. 2. These auxiliary levers d and d are provided with downwardly projecting extensions d* each of which is connected by means of a wire, rod or the like d with a coperating element in each motor or motor group which is to beiregulated or controlled. The main lever c is movable between and guided by stationary segmental members f and f having their opposite ends secured upon the frame a and curved in arcs having the axis b for a center as shown best in Fig. 1, said members f and f being provided on their outer surfaces with teeth f2 and f3 which project toward the auxiliary levers d and d. At their lower curved edges the segmental members f and f are provided with teeth f* and f5 which cooperate with projections c2 on the main lever c to maintain the latter in a given po sition. In addition to this the main lever c at points above the segmental members f' and f is provided on its opposite faces with curved disks c having centrally located notches c2 and 'c3 projecting respectively toward the auxiliary levers d and d', this arrangement being most clearly shown in Fig. 8. teeth or projections d2 and cl3 located in registry with the teeth f2 and f3 and extend-` ed upwardly so as to also lie opposite the disks c of the main lever c as shown in Fig. 2. The auxiliary levers d and d. are further preferably provided at their upper ends with suitable operating handlesv d".

In the normal condition of the parts the teeth d2 and d3 of the auxiliary levers d and d 'are in engagement respectivelywith the' The auxiliary levers d and d carry being 'at the same time in a normal position 1 in whichthe'curved projections o are out of line wrtli said auxiliary levers d and d.

As before'stated the main lever c is maintainedm a given position through the cooperatlon of the teeth'M-le5 and the projection e.

If it is desired to adjust or regulate the motors or motor groups independently of each other, the auxiliary levers d and d are actuated. These auxiliary levers are constructed so as to be somewhat resilient and may thus be first manipulated transversely to disengage the teeth d2 and da from the teeth f2 and f3 of the segmental members f and f after which said auxiliary levers may be pivotally moved on the axis b and relatively to the main lever to produce a pull or a push on-the wires or rods d whereby the elements connected with said wires or rods al are operated to bring about the desired adjustment or regulation of each motor or motor group independently of the others. If only one motor or motor group is to be regulated it is simply necessary to manipulate the particular auxiliary lever connected therewith, in the manner above set forth,`

into engagement with the teeth fz- 3 of the members j' and f and lock said auxiliary levers against movement. The teeth f2 and f3 may extend along the members f and f so that the auxiliary levers may be held in any adjusted position through the medium 0f the teeth d2 and d3.

If the motors or motor groups are to be concurrently regulated the main lever c is first released by disengaging the project-ion c from the teeth f* and f located on the lower edges of the segmental members f and f in any suitable and convenient manner. After this has been done the said main lever c is moved in the arc of a circle on the axis b which will first bring the curved peripheriesof the disks c. into engagement with the upwardly extended portions of the teeth d2 and d3 of the auxiliary levers ci and el. A continued actuation of said main lever c will cause the said peripheries of said disks c to exert a camming action on said teeth cl2 and d3 and will in consequence ygradually force said auxiliary levers d and el apart and thus disengage the teeth d2 and lthereof from the teeth f2 and f3 whereby said. auxiliary levers are freed from restraint. As soon as the relative movement of the main lever c is suilicient to bring the notches o2 and c3 of the disk c into registry with the teeth l2 and Z3 the latter owing to the resiliency of said auxiliary levers will snap into said notches o2 and c3 and thereby couple the auxiliary levers d and d and the mam lever c together. As the actuation of the main lever is now continued the auxihary levers d and cl will be concurrently carried along in a pivotal movement and will thus bring about a simultaneous regulation of all of the motors or motor' groups as will be readily apparent. A return actua- 'tion of the main lever c will carry the auxiliary levers d and d' back with it, the latter being disconnected from said main lever c by vdisengaging the teeth d2 and d3 from the notches c2 and c3 and permitting them to snap back into engagement with the teeth f2 and f3 to again lock said auxiliary levers d and d in their normal positions. In the meantime the projection c in coperation with the teeth ,f4 and f5 now again secures the main lever c against movement. The teeth f4 and f5 may be located along the entire lower edges of the members f and f so that the main lever c and connected parts may be held in any adjusted position by means of the projection c.

The form of our improvement shown in Figs. 4:-6 is intended to control and regulate four individual'motors or four motor groups and in addition to the parts included in the first form comprises arms c4 and c5 which are secured upon the shaft b to rotate therewith andare movable respectively between stationary segmental members f and f7 similar to the members f4 and f5 and likewise carried by the support or frame a which latter correspondsl to the frame a and is also supported in operative position in any convenient manner. The arms o4 and c are located alongside of the auxiliary levers d and d and at their upper ends carry semi-circular disks o and c7 having notches es and c similar to the notches c2 and c3 of the disk c and preferably arranged in line therewith. This form of my improvement further includes additional auxiliary levers d4 and d5 located alongside and outside of the arms c4' and c5 respec# tively and corresponding to the levers d and d of the form first described, said auxiliary levers d4 and d5 being also loosely mounted on the shaft b so as to be movable thereon and preferably also having their free ends provided with operating handles 03. The said additional auxiliary levers al* and d5 are further also formed with downwardly projecting extensions d* each of which is operatively connected by means of a rod,

v Wire or the like d with one of the motors or motor groups. The additional auxiliary ,levers also carry teeth d and al? corresponding to the teeth d2 and da of the auxiliary levers d and d and adapted to coperate in the same way with the notches es and c of the semi-circular disks c and c7 andwith teeth f8 and f carried respectively by one of the segmental members f6 and f7 as shown in Figs. 5 to 8 inclusive and corresponding to the teeth f2 and f3. It will be understood that the auxiliary levers d* and d5, like the auxiliary levers d and d', are constructed so as to be somewhat resilient. In all other respects the present form may be the same as the form of our improvement first described.

When it is desired to regulate or control any one of the motors or motor groups independently of the others, the particular auxiliary lever (Z, a", (Z4 or (Z5 which is operatively connected with the particular motor or motor groups to be regulated is first released by pressing said lever transversely against its resiliency to disconnect the teeth (Z2, (Z3, (/Z6 or (Z7 from the teeth f2, f3, f8 or f" as the case may be. After this has been done the particular auxiliary lever is simply rocked on the shaft Z) and moved between its cooperating segmental members to actuate its extension (ZX and connected rod, wire or the like aZ which results in a regulation or control in the desired manner of the particular motor or motorgroup in question. It will thus be seen, as shown in Figs. 7 and 8, that the auxiliary levers (Z, (Z, (Z4 and (Z5 are capable of being actuated independently of each other and of the main lever c and arms c4 and c? which latter are fast upon the shaft b and thus movable with the main lever c, so that the motors or motor groups may be individually or independently regulated in any desired manner. After the particular auxiliary lever or levers have been independently operated to bring about the desired regulation they may be returned to normal position by an actuation in a reverse direction to again cause the teeth d2,

(Z3, (Z6 or (Z7 according to which of the auxiliary levers is being manipulated to snap back into engagement with the coperating teeth f2, f3, f8 or fg carried by the respective segmental members, and thus again lock the auxiliary lever or levers in normal position.

If a concurrent or simultaneous regulation or adjustment of all of the motors or motor groups is desired the projection c is first disengaged from the teeth f4 and f5 of the segmental members f and f to release the main lever c after which said main lever c is moved in the arc of a circle between the said members f and f. This movement of the main lever c will rock the shaft Z) and owing to the fact that the arms 04L and 05 are fast upon said shaft will consequently also Amove said arms incircular arcs between their respective segmental members f and f7. As sald main lever 0 and arms c4 and (f' are thus actuated the peripheries of the c and arms c4 and 05 will nally bring the notches c2, 03,'08 and 09 of the disks v c c6 and c7 into registry respectively with the teeth (Z2, (Z3, (Z6 and (Z7 which as a result will all snap into said notches as shown in Fig. 6 and thus operatively connect the auxiliary levers (Z, (Z, (Z4 and Z5 with the main lever c and arms c4 and c5. In this condition of the parts all of the auxiliary levers are coupled to the main lever c so that a further operation of the latter will cause a corresponding and concurrent actuation of all of said auxiliary levers and 'thus bring about a concurrent or simultaneous regulation or adjustment of all of the motors and nrotor groups. A reverse actuation of the main lever c will finally return all of the parts to their initial positions in which the auxiliary levers are again capable of being independently operated or in connection with the main lever as may be desired. With this last form it is further possible to manipulate two of the auxiliary levers, for instance (Z and (Z5 independently of each other and then concurrently operate the other two levers (Z and (Z by an actuation of the main lever c as indicated in Fig. 6. Any other desired combination is possible with equal efliciency and facility. It will be noted that Fig. 2 of the drawings shows the parts in normal position while Fig. 5 illustrates all of the auxiliary levers coupled to the main lever c. In this last form also the teeth f2, f3, f8 and fi as well as the teeth f and f may extend throughout the respective segmental members f, f', f and f7 so that the auxiliary vlevers individually or the main lever when coupled to said auxiliary levers may be maintained in an adjusted position in the same way as explained with respect t0 the form first described.

It will thus be seen that in both forms of our improvement a regulation or adjustment of each motor or motor groups independently of all others is readily possible, while at the same time said motors and motor groups may be simultaneously or-concurrently regulated or adjusted when desired, in a simple and efficient manner. It will be apparent that our improvement may be readily adapt- -ed for individually or concurrently regulating or adjusting more than four motors or motor groups with equal efficiency by simply carrying out the arrangement shown in Figs. 4 6. It will of course be understoodA that the peripheries of the disks c', ce and c7 may be otherwise found than as curves as long as said peripheries serve to exert the desired camming action lon the'auxiliary levers.

If desired both forms of our improvement may include additional members having their ends connected with the frames a and a for bracing or stiffening same. In the form first described the main lever c may be loose or fast on the shaft as desired A while inthe form last described the said lever c is preferably secured to said shaft b to rotatetherewith, although other equivalent arrangements adapted to produce the desired results may be substituted if desired. 1t will further be understood that the apparatus is set up within easy reach of the operator and that the same may be utilized for regulating and controlling any type of driving or other mechanisms where an individual and a concurrent adjustment is desired. While we have described our improvement as particularly adapted for use in connection with flying apparatus, airships and the like, it will be obvious that the same is equally well adapted for many other uses.

Various changes in the specific form shown and described may be made within the scope of the claims. without departing from the spirit of our invention.
